The large capacity 1.5 Litre Wide-Mouth Tritan Silo is a hard plastic water bottle which is solid and durable with no bend or flexibility, so it won't get crushed in your pack. Graduation markings on the side help you to keep track of your fluid intake or serve as a useful guideline when mixing up an energy drink in your Nalgene.

The convenient loop-top design means you'll never lose the lid, the wide mouth makes adding ice cubes a snap and the opening accommodates most water filters.
